Michael C Preston, DDS

Dr preston is fantastic! I am extremely picky when it comes to a Dentist. When I found Dr. Preston I was so happy! He takes his time with me and answers any questions I have. He is extremely thorough with his work and genuinely cares about his patients. I always have his undivided attention and never feel like he is rushing through my appointment. Dr preston is always on time and that is HUGE to me. His staff is very friendly as well. Recommended 10 stars!

This dentist is awesome… not to mention honest! This is one dentist you will never have to worry about getting ripped off from. My daughter was terrified of dentist until Dr. Preston. We have both been going here ever since… Love the entire staff. Till this day I have never received a bill for anything! My Delta Dental is the best! LOVE THEM and so will you! If your sensitive about who touches your mouth … or just sensitive period this is really the Dentist for you :)

I am so glad I finally found a dentist who is professional, thorough, smart, funny and caring. He’s very good keeping me aware of how my teeth are doing (not that I always want to know!) and helping me keep my teeth and gums healthy. His staff is excellent as well. A great group of people who are welcoming and efficient at the same time. I’ve never yet had to wait to be seen when I show up for an appointment, either. This guy is the best.

I have been seeing Dr. Preston since he established his practice in Castro Valley years and years ago, and have never actually considered going to a different dentist, despite the fact that I now live across the Bay and it is a fairly long drive to get there for me now… it is worth the drive for me… here’s why:
1) I challenge you to find a more friendly, caring or courteous staff than what you will find at Dr. Preston’s office. Everyone is friendly and extremely oriented to maximize the patient’s comfort at all times, from reception to assistants to Dr. Preston himself.
2) Dr. Preston is concerned not only with the immediate dental problems/​issues but thinks well ahead and plans for the best long term care and preventative solutions. He sees potential issues a long ways in advance which allows you to prepare yourself both mentally and financially for upcoming procedures, or will make suggestions on how to avoid those issues in the long term (e.g., he suggested a night guard to me as I was grinding my teeth and this was going to lead to a lot of problems down the line if left unresolved… it was an easy and low-​cost option which put an immediate stop to the damage).
3) Your care is tailored specifically to your individual needs, medical conditions/​concerns, and preferences, to the best extent possible. This is not a «one size fits all» dentist and Dr. Preston is always willing and able to come up with alternatives if the first approach isn’t going to work best for the individual.
All in all, if you are just looking for a dentist to be like a «Supercuts» or «Jiffy Lube» for your mouth, Dr. Preston is certainly more than sufficient and his individualized attention is going to blow you away if you give him a chance. But if you are like me and realize that dentists and doctors are more than just any other «business», and your expectations extend beyond getting an «accurate quote» over the phone, then look no further than Dr. Preston’s office. You’ll be happy you did

Dr. Preston really cares about his patients. You just feel it when you walk in – He is so thorough in explaining everything that he’s doing and why. He takes the time to get to know who you are, and you don’t feel like «just another mouth» in his chair. Everyone in the office treats you with respect and courtesy, and you never have to wait long. When you are in his chair, he rarely leaves to go running off to some other room – you get his full attention. He’s one of the best dentists ever!

I have been going to Dr. Preston for 4 years. I originally heard about him from my brother who is a dental lab technician. I told my brother I was dissatisfied with my current dentist and he said I should try Dr. Preston. He told me that Dr. Preston sent the most detailed specifications of any dentist and that Dr. Preston cared about the quality of his work so much that he would frequently come into the lab to make adjustments to fixtures personally. My brother said the lab served over 100 dentists and no one else was that thorough. I am very pleased with my experience with him. He explains everything he is doing and why he his doing it while he is doing it. When I needed a filling in a front tooth Dr. Preston tested the shade in 3 different light sources includeing going outside in the sun! He ended up going with a custom blend that was in-​between shades. The filling is perfect. I can’t even tell where it begins and ends so I know no one else can. I never hesitate to smile. Thanks Dr. Preston!

If you are looking for a special dentist who will treat you with respect, explain everything thoroughly, and do a great job technically, this is the guy you want. He doesn’t keep you waiting like some offices do, and he spends as much time with you as you need. He’s a perfectionist, which suits me just fine. He uses high– quality, local dental labs. The quality shows in the cases he does – They look amazing! I have been seeing him for over twenty-​five years, and I should know a good dentist – I’m a dental professional too.

Wow what a great experiance! I have had such a hard time trying to find a dentist. One day my luck had changed. I came along Dr Preston in Castro Valley and I was set! He was so friendly and so easy to talk with, His staff members are great! Always in a happy mood and ready for me as soon as I walk in the door. I had to have 3 fillings and I was so worried, Preston had such a great way to numb you that I didnt even feel it! He even allowed me to wear my earplugs because I hate the sound of the drill! All around Dr. Preston changed my mind about going to the dentist. My experiance was great and I actually cant wait to go back. Would definitly tell others about him!
